Description

Technical Field

[0001] This utility model belongs to the technical field of locker accessories, specifically relating to a hinge transmission component and a hinge. Background Technology

[0002] In modern cabinet hinge design, the integration of buffer mechanisms often leads to a significant increase in product height, inevitably affecting the overall aesthetics of the space and causing interference when retrieving items. This problem is mainly determined by its structural principle. Taking direct-drive buffer hinges as an example, the buffer must be installed at an angle to maintain effective contact with the swinging arm. This installation method directly increases the vertical space occupied by the hinge, causing it to protrude 15mm-25mm from the cabinet side wall. For indirect-drive buffer hinges, the design concept of using a folding bracket as a transmission medium avoids the angled installation of the buffer, but introduces a new height space problem. When the folding bracket is unfolded, sufficient swing space needs to be reserved. This space requirement, combined with the size of the buffer itself, means that the overall height of the hinge cannot be reduced. It is particularly noteworthy that, to achieve reliable transmission, the folding bracket must maintain a certain structural strength, which further limits the possibility of its flattening, ultimately creating a design contradiction between height and structural strength.

[0003] In existing technologies, the integration of buffer mechanisms in cabinet hinges, whether direct-drive or indirect-drive, results in a significant increase in product height, which is not conducive to the flattening design of the hinges. Utility Model Content

[0004] The first objective of this invention is to overcome the problem that the buffer mechanism of cabinet hinges in the prior art causes a significant increase in product height, and to provide a hinge transmission component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hinge transmission component includes a component body, the front end and rear end of the component body are respectively set as a rocker arm connection end and a buffer connection end, the bottom surface of the component body is provided with a sliding plane, the side surface of the component body is provided with a pressure-bearing groove, the side area between the pressure-bearing groove and the buffer connection end is a plane and is set as a first abutting surface, and the rear side wall of the pressure-bearing groove is an inclined surface and is set as a second abutting surface.

[0007] This invention provides a novel design for hinge transmission components, offering a fresh approach to existing hinges. The component body connects to a connecting rod and a buffer at its front and rear ends, respectively. The hinge's drive mechanism is positioned near the pressure-bearing groove. The component body abuts against the elastic element of the drive mechanism via a first and second abutment surface. When it abuts against the elastic element via the first abutment surface, the elastic element compresses and accumulates elastic force. As the component body moves backward and abuts against the elastic element via the second abutment surface, the elastic force is released and acts on the second abutment surface, providing the component body with the driving force to continue moving backward. Thus, when the connecting rod swings around the connecting fulcrum, the component body performs a horizontal reciprocating motion and selectively triggers the buffer via the pressure-bearing groove. This allows the buffer, component body, and drive mechanism to be horizontally arranged on the hinge's connecting arm, thereby reducing the hinge structure's height and making it flatter overall while maintaining the buffering effect.

[0008] Furthermore, the connecting end of the rocker arm is provided with a groove with an open front end, and hinge shaft holes are provided on opposite sides of the groove. In practical applications, the hinge shaft holes are used to assemble and install the shaft, and the component body is connected to the transmission arm of the buffer device through the mounting shaft.

[0009] Furthermore, the groove is located on the front end of the component body near the pressure-bearing groove. In practical applications, the buffer device is set on one side of the connecting arm, and the other side of the connecting arm is used to assemble the drive mechanism. In this solution, the groove is set on the side near the pressure-bearing groove, making it biased towards the center, so that the transmission arm can extend linearly from the groove to the swing arm of the hinge.

[0010] Furthermore, the component body includes a reinforcing block and a shell. The pressure-bearing groove, recess, and sliding plane are provided on the shell. The reinforcing block is embedded in the shell, and the shell has a groove to cooperate with the reinforcing block. The shell is made of plastic. In this design, the shell is made of plastic and has a groove to cooperate with the reinforcing block, ensuring a tight fit between the two. The plastic material has a low coefficient of friction, which reduces frictional resistance with the connecting arm and drive mechanism during the sliding process of the component body, reducing noise and energy loss, making the movement of the component body smoother, and improving transmission efficiency.

[0011] Furthermore, the reinforcing block is a precision-cast metal part. In this solution, the reinforcing block is made of precision-cast metal, which has high strength and can withstand large forces and stresses, ensuring the structural stability of the component body during reciprocating motion and preventing deformation or damage, thereby improving the reliability and service life of the entire hinge transmission component.

[0012] Furthermore, the reinforcing block includes a third connecting wall, and the rear end of the outer shell is provided with a third mounting groove to cooperate with the third connecting wall. The third connecting wall is embedded in the third mounting groove and serves as the connection end of the buffer. In this solution, the component body is reliably connected to the buffer through a high-strength, high-stability reinforcing block. This connection method greatly enhances the overall structural stability of the component body, enabling it to maintain structural integrity and stability when subjected to complex external forces, such as the reciprocating impact force during hinge transmission and the reaction force of the buffer, effectively preventing structural deformation or damage caused by local stress concentration.

[0013] Furthermore, the reinforcing block includes a first connecting wall, a second connecting wall, and a fourth connecting wall. The lower ends of the second connecting wall and the fourth connecting wall are respectively connected to one side of the front end of the first connecting wall and are provided with hinge shaft holes. The lower end of the third connecting wall is connected to the rear end of the first connecting wall. The outer shell is provided with a first mounting groove, a second mounting groove, and a fourth mounting groove to cooperate with the first connecting wall, the second connecting wall, and the fourth connecting wall. The second mounting groove is located on one side of the groove.

[0014] Another objective of this invention is to provide a hinge comprising a base assembly, a hinge cup, and a transmission mechanism. The base assembly and the hinge cup are connected via the transmission mechanism, which includes a buffer device and a swing mechanism. The buffer device comprises a horizontally arranged transmission arm, a buffer, and a hinge transmission component as described above. The front and rear ends of the hinge transmission component are respectively connected to the buffer and the transmission arm. The transmission arm is connected to the rear side of the swing mechanism. When the swing mechanism swings around the connecting fulcrum, it drives the hinge transmission component to perform horizontal reciprocating motion via the transmission arm, causing the component body to selectively trigger the buffer.

[0015] This invention achieves a compact horizontal transmission scheme by horizontally arranging components such as the buffer and hinge transmission mechanism. This significantly reduces the overall height of the hinge, making the cabinet sidewalls flatter and more aesthetically pleasing, while avoiding the collision problems associated with traditional protruding hinges. The design optimizes the connection between the transmission arm and the swing mechanism, ensuring the buffer force is evenly transmitted horizontally. This not only improves the stability and smoothness of door opening and closing but also enhances the structure's load-bearing capacity, making it particularly suitable for heavy-duty doors. Furthermore, the horizontally arranged buffer device provides a more rational force distribution, reduces component wear, and extends service life. Its flat structure simplifies installation and improves adaptability, allowing for wide application in modern minimalist furniture and various customized scenarios, maximizing space utilization while ensuring performance.

[0016] Furthermore, the base assembly includes a base body, a connecting arm, and an outer cover. The base body has a base receiving portion and an installation structure. The base body is fixedly connected to the cabinet through the installation structure. The connecting arm is slidably mounted on the base receiving portion. The transmission mechanism is located on the connecting arm. The connecting arm is connected to the hinge cup through the swing mechanism. The outer cover is located on the base body.

[0017] Furthermore, a drive mechanism is included, mounted on the connecting arm. The side of the component body abuts against the drive end of the drive mechanism. Upon receiving backward pressure, the buffer device moves backward as a whole, triggering the drive mechanism to provide a backward driving force for the buffer device. This solution adds a drive mechanism that works in conjunction with the buffer device. When the buffer device receives backward pressure, the drive mechanism provides it with a backward driving force, achieving automatic buffering and driving during the door closing process, reducing the force required for manual operation by the user. Especially when the door is close to closing, the two work together to automatically complete the closing action, requiring only a gentle push from the user. Attached Figure Description

[0041] Example 1:

[0042] See Figure 1-3 As shown, this embodiment discloses a hinge transmission component, including a component body. The front end and rear end of the component body are respectively set as a swing arm connection end and a buffer connection end. The bottom surface of the component body is provided with a sliding plane, and the side surface of the component body is provided with a pressure-bearing groove 451a. The side area between the pressure-bearing groove 451a and the buffer connection end is a plane and is set as a first abutment surface. The rear side wall of the pressure-bearing groove 451a is an inclined surface and is set as a second abutment surface.

[0043] The aforementioned transmission connection includes a groove 43 with an opening at the front end, and hinge shaft holes are provided on opposite sides of the groove 43. In practical applications, the hinge shaft holes are used to assemble and mount the mounting shaft 614, and the component body is connected to the transmission arm 47 of the buffer device 4 through the mounting shaft 614.

[0044] The aforementioned groove 43 is located on the front end of the component body near the pressure-bearing groove 451a. In practical applications, the buffer device 4 is set on one side of the connecting arm 6, and the other side of the connecting arm 6 is used to assemble the drive mechanism 7. In this scheme, the groove 43 is set on the side near the pressure-bearing groove 451a so that it is biased towards the center, so that the transmission arm 47 can extend linearly from the groove 43 to the swing arm of the hinge 1.

[0045] The aforementioned component body includes a reinforcing block 45 and a housing 46. A pressure-bearing groove 451a, a recess 43, and a sliding surface are provided on the housing 46. The reinforcing block is embedded in the housing 46, and the housing 46 has a groove to accommodate the reinforcing block. The housing 46 is made of plastic. In this design, the housing 46 is made of plastic and has a groove to accommodate the reinforcing block, ensuring a tight fit between the two. The plastic material has a low coefficient of friction, which reduces frictional resistance between the component body and the connecting arm 6 and the drive mechanism 7 during sliding, reducing noise and energy loss, making the movement of the component body smoother, and improving transmission efficiency.

[0046] The aforementioned reinforcing block is a precision-cast metal part. In this design, the reinforcing block is made of precision-cast metal, which has high strength and can withstand large forces and stresses, ensuring the structural stability of the component body during reciprocating motion and preventing deformation or damage, thereby improving the reliability and service life of the entire hinge transmission component.

[0047] The aforementioned reinforcing block includes a third connecting wall 453. The rear end of the outer shell 46 is fitted with the third connecting wall 453 and has a third mounting groove 463. The third connecting wall 453 is embedded in the third mounting groove 463 and serves as the connection end of the buffer. In this design, the component body is reliably connected to the buffer through the high-strength, high-stability reinforcing block 45. This connection method greatly enhances the overall structural stability of the component body 41, enabling it to maintain structural integrity and stability when subjected to complex external forces, such as the reciprocating impact force during hinge transmission and the reaction force of the buffer 48, effectively preventing structural deformation or damage caused by localized stress concentration.

[0048] The aforementioned reinforcing block includes a first connecting wall 451, a second connecting wall 452, and a fourth connecting wall 454. The lower ends of the second connecting wall 452 and the fourth connecting wall 454 are respectively connected to one side of the front end of the first connecting wall 451 and are provided with corresponding hinge shaft holes. The lower end of the third connecting wall 453 is connected to the rear end of the first connecting wall 451. The outer shell 46 is provided with a first mounting groove 461, a second mounting groove 462, and a fourth mounting groove 464 to cooperate with the first connecting wall 451, the second connecting wall 452, and the fourth connecting wall 454. The second mounting groove 462 is located on one side of the groove 43.

[0049] This invention provides a new design concept for the hinge transmission component, which connects a buffer 48 and a connecting rod to the front and rear ends of the component body, respectively. The drive mechanism 7 of the hinge 1 is located on the side near the pressure groove 451a. The component body abuts against the elastic element 71 of the drive mechanism 7 through a first abutment surface and a second abutment surface. When it abuts against the elastic element 71 through the first abutment surface, the elastic element 71 compresses and accumulates elastic force. When the component body moves backward and abuts against the elastic element 71 through the second abutment surface, the elastic force of the elastic element 71 is released and acts on the second abutment surface, providing a driving force for the component body to continue moving backward. In this way, when the connecting rod swings around the connecting fulcrum, the component body performs horizontal reciprocating motion and selectively triggers the buffer 48 through the pressure groove 451a, so that the buffer device 4, the component body, and the drive mechanism 7 can be horizontally arranged on the connecting arm 6 of the hinge 1, thereby reducing the height of the hinge structure and making it flatter overall while ensuring the buffering effect.

The transmission arm 47 is connected to the rear side of the swing mechanism 3. When the swing mechanism 3 swings around the connecting fulcrum, it drives the hinge transmission component to make horizontal reciprocating motion through the transmission arm 47 and causes the component body 41 to selectively trigger the buffer 48.
